Positioning Control Monitor Function

Scroll monitor

The scroll monitor is a function used to monitor up to 256 items of positioning start history such as servo programs, JOG start,
and Motion dedicated PLC instructions. This function applies to controls for which the start accept flag turns ON. (G-code
control is not recorded in the history.)
Scroll monitor information is retained even when the Multiple CPU system power supply is turned OFF, or when reset. The
scroll monitor is cleared by executing the scroll monitor [History clear] or "Motion CPU memory clear" from MT Developer2.
The following items are displayed on the scroll monitor.
